'Big Brother' down as NFL return dominates Wednesday ratings

However, the game between the Cowboys and the Giants was 15% lower than last year's broadcast. It brought an 18-49 demo rating of 8.7 (21.81 million viewers) between 8-11pm. The lead-in NFL Kickoff show was also down 14%, with a 5.5 rating (14.32m) at 8pm.

As a result, CBS's Big Brother dropped 9% from last week to 2.1 (6.09m) at 8pm, winning the night for usual programming.

Fox's So You Think You Can Dance? fell 7% to 1.4 (4.14m) at 8pm.

The CW's Oh Sit! was level with last week's rating of 0.4 (1.14m) at 8pm.

The continued coverage of the Democratic National Convention earned a 0.9 rating on both CBS and ABC at 10pm.

However, the figures for both the DNC and the NFL game may be adjusted at a later date due to time differences across the US.
